Item A Non – Enzymatic Hydrogen Peroxide Biosensor Based on RGO/MnO2 Nanocomposite(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Fahad Abbas; P19-RPH-002; Dr. Muhammad Hammad Aziz; LHR TP 6366Another electrocatalyst, RGO/MnO2 half breed nano structure was effectively incorporated for the non-enzymatic discovery of H2O2. The morphological portrayal was inspected by X-Ray Diffractometery (XRD), fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The RGO/MnO2 based terminals demonstrated high electrochemical action in order to recognize the hydrogen peroxide in soluble solution. The non-enzymatic biosensors showed great execution alongside small operational potential, great affectability, little recognition boundary, and long haul dependability, that can be ascribed to the great surface area of RGO accommodating the statement of MnO2 nanoparticles. These outcomes show that , fresh Nano composite along great surface territory and electrocatalytic action offers extraordinary guarantee for new class of nanostructured terminal for non-enzymatic biosensor also, energy change applications. Here, in this experimental study, we have synthesized and characterized RGO-MnO2 by X-ray Diffractometery (XRD) , Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM) for structural and morphological studies.Item GO/MnFe2O4mediated Electrochemical Biosensing for Monitoring Glucose(Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) Muhammad Ashfaq; CIIT/SP19-RPH-039/LHR; Dr. Muhammad Hammad Aziz; LHR TP 6376GO-MnFe2O4 nanoparticles have been used as a drug delivery in medical, biosensing and bioimaging. In this study, GO-MnFe2O4 nanoparticles were prepared by Co precipitation method with variation in stirring time. The prepared material was characterized by XRD, SEM and FTIR. Single phase composite material examined by XRD and average crystallite size found to be 60nm.SEM images shows the proposed material is homogeneous and dense. The working electrode GO-MnFe2O4 was prepared successfully using glassy carbon. The electrochemical measurement is performed for different concentration of glucose. Increment in glucose concentration gives the linear response in form of higher potential.
